The international environmental responsibility has became a very important issue for the international community and especially for Lithuania caused of the specific geographical and geopolitical situation.The subject of the master's thesis is the principles of international environmental responsibility - principles, setting up the main guidelinesfor the development of the international legal norms, which describes international responsibility arising out of the environmental harm as well as relations among states.

Particularly in the health domain, humans thrive to reach an equilibrium between maximizing pleasure and minimizing harm. I propose that a cognitive strategy people employ to reach this equilibrium is the activation of Compensatory Health Beliefs (CHBs). CHBs are beliefs that the negative effects of an unhealthy behavior can be compensated for, or "neutralized," by engaging in another, healthy behavior. "I can eat this piece of cake now because I will exercise this evening" is an example of such beliefs. This thesis presents a theoretical framework which aims at explaining why people create CHBs and how they employ CHBs to regulate their health behaviors. The model extends current health behavior models by explicitly integrating the motivational conflict that emerges from the interplay between affective states (i.e., cravings or desires) and motivation (i.e., health goals). The first study includes a psychometric scale that measures CHBs in the general population and provides data on its reliability and validity. The results showed that scores on the scale were uniquely associated with health-related risk behaviors and symptom reports and could be differentiated from a number of related constructs. Holding CHBs may hinder individuals from acquiring healthier lifestyles, for example lose weight or exercise. The second large-scale study of this thesis aimed at studying CHBs in adolescents with type 1 diabetes. It is proposed that in this population, CHBs might interfere with treatment adherence. If compensatory behaviors fail to compensate for the maladaptive behaviors, poor blood glucose control and related health problems may arise. To investigate this further, I developed and validated a CHB scale specific to type 1 diabetes. The scale was validated in a sample of adolescents with type 1 diabetes. Results showed that holding maladaptive compensatory health beliefs was associated with poorer blood glucose control and poorer adherence to self-care behaviors while adaptive CHBs were associated with better blood glucose control and better adherence to treatment behaviors. Specifically targeting CHBs in an intervention could improve adherence to treatment and therefore the long-term health of this population. Future research as well as the implications for possible interventions are explicitly being discussed.

While not exactly back room political bargaining, the traditional use of cooperation has been by moral theologians attempting to define the level of cooperation for a particular situation. This chosen definition, in turn, may help focus the range of appropriate actions in response to the situation's circumstances. In this customary usage, an organization's associates (employees) may assist the implementation of relevant responses to a cooperation analysis, whether the issue is clinical or organizational in nature. They have not been integral to the decision-making process - until now. <br>Cooperation has been the proverbial candle under the bushel (Matthew 5:15). This paper proposes the involvement of organizations' associates not only for decision-making and discernment, but for their own moral development. The foundation of this thesis is not only that organizations are moral agents, but also that organizations are reflective of the moral development of their associates when they exercise their agency. Using this model, this theory advances a use of the principle of cooperation by interpreting cooperation as a function of moral development for advancing associates. Advancement, in this case, means that, optimally, the process will expose participants to individuals in various stages of moral development, challenge them in appropriate ways, and enhance their moral development as characterized by Lawrence Kohlberg and Carol Gilligan. Even if participants do not advance in their moral development, the model proposed here will form participants in moral decision-making within the Catholic moral tradition. To a lesser degree, it is also a useful ministry discernment tool if appointed to discriminate responses to some of the individual and organizational issues (topics) mentioned above. / McAnulty College and Graduate School of Liberal Arts / Health Care Ethics / PhD / Dissertation

In this thesis I present a new numerical scheme for 2.5-D/3-D direct current resistivity modelling in heterogeneous, anisotropic media. This method, named the ‘Gaussian quadrature grid’ (GQG) method, co-operatively combines the solution of the Variational Principle of the partial differential equation, Gaussian quadrature abscissae and local cardinal functions so that it has the main advantages of the spectral element method. The formulation shows that the GQG method is a modification of the spectral element method and does not employ the constant elements and require the mesh generator to match the earth’s surface. This makes it much easier to deal with geological models having a 2-D/3-D complex topography than using traditional numerical methods. The GQG technique can achieve a similar convergence rate to the spectral element method. It is shown that it transforms the 2.5-D/3-D resistivity modelling problem into a sparse and symmetric linear equation system, which can be solved by an iterative or matrix inversion method. Comparison with analytic solutions for homogeneous isotropic and anisotropic models shows that the error depends on the Gaussian quadrature order (abscissae number) and the sub-domain size. The higher order or smaller the subdomain size employed, the more accurate the solution. Several other synthetic examples, both homogeneous and inhomogeneous, incorporating sloping, undulating and severe topography are presented and found to yield results comparable to finite element solutions involving a dense mesh. The thesis also presents for the first time explicit expressions for the Fréchet derivatives or sensitivity functions in resistivity imaging of a heterogeneous and fully anisotropic earth. The formulation involves the Green’s functions and their gradients, and is developed both from a formal perturbation analysis and by means of a numerical (finite element) method. A critical factor in the equations is the derivative of the electrical conductivity tensor with respect to the principal conductivity values and the angles defining the axes of symmetry; these are given analytically. The Fréchet derivative expressions are given for both the 2.5-D and the 3-D problem using both constant point and constant block model parameterisations. Special cases like the isotropic earth and tilted transversely isotropic (TTI) media are shown to emerge from the general solutions. Numerical examples are presented for the various sensitivities as functions of the dip angle and strike of the plane of stratification in uniform TTI media. In addition, analytic solutions are derived for the electric potential, current density and Fréchet derivatives at any interior point within a 3-D transversely isotropic homogeneous medium having a tilted axis of symmetry. The current electrode is assumed to be on the surface of the Earth and the plane of stratification given arbitrary strike and dip. Profiles can be computed for any azimuth. The equipotentials exhibit an elliptical pattern and are not orthogonal to the current density vectors, which are strongly angle dependent. Current density reaches its maximum value in a direction parallel to the longitudinal conductivity direction. Illustrative examples of the Fréchet derivatives are given for the 2.5-D problem, in which the profile is taken perpendicular to strike. All three derivatives of the Green’s function with respect to longitudinal conductivity, transverse resistivity and dip angle of the symmetry axis (dG/dσ₁,dG/dσ₁,dG/dθ₀ ) show a strongly asymmetric pattern compared to the isotropic case. The patterns are aligned in the direction of the tilt angle. Such sensitivity patterns are useful in real time experimental design as well as in the fast inversion of resistivity data collected over an anisotropic earth. / Thesis (Ph.D.) -- University of Adelaide, School of Chemistry and Physics, 2009

The documentary letters of credit transaction is the most common method of payment for goods in international trade. Its use has been considered so important that it is referred to as the �lifeblood� of international commerce. The purpose of this thesis is, through analysing the present regime of documentary credit established under the The Uniform Customs and Practice for Documentary Credits, 1993 Revision (�UCP�), to identify the rights and duties of all parties in such transactions and the reasons for the frequent occurrence of fraudulent activities associated with the documents required under the credits. It identifies that the present system fails to either encourage or implement substantial realisation of �reasonable care� or �good faith� on the part of the banks, or realisation of the requirement of �good faith� from beneficiaries. As a result, the independence principle has been left without substance, with resulting huge opportunities for fraudsters to cheat on the documents and obtain payment without the need to actually perform their duties to banks and buyers. Such issues have become more acute against the background of an underlying shift in the allocation of risk between the respective parties to letters of credit. There has been a depreciation in the value of the primary document of title and security held by the issue, the bill of lading, with the advent of container shipping. As the letter of credit system is wholly dependent on the integrity of the documents, it is being undermined by these developments. This has represented a shift in the traditional scheme of risk allocation from the seller to the bank. In practice, banks have taken countermeasures by insisting that applicants provide other types of collateral, and by subjecting applicants to rigorous credit checks. Thus, applicants ultimately have had to bear the brunt of costs associated with this reallocation of risk. It will be demonstrated that the UCP does not incorporate adequate or clear enough duties to be exercised on the part of issuers toward applicants, and severely restricts the applicant�s right to sue if the issuer has wrongfully honoured. Ultimately, a balance must be struck between the desirability of protecting the applicant from the beneficiary�s fraud against the benefits gained by maintaining the letter of credit as a commercial instrument and business device. Obviously, there is public interest in protecting both of these commercial values. This thesis advocates that a mechanism in addition to the fraud exception must be introduced to safeguard the system against the ramifications of these changes � increased fraud. The thesis is structured into five chapters. Chapter 1 sets out to demonstrate the circumstances under which the respective risks are borne by each participant in the letter of credit transaction, and how developments in trade practice have caused the burden of certain of these risks among the parties to a letter of credit transaction to shift. Chapter 2, after briefly visiting the historical origins of the letter of credit and the birth of the UCP, explores the implications of the dominance of banking interests over the drafting and interpretation of the UCP, how the UCP has in practice excluded the intrusion of other sources of law and the general reluctance of courts to intervene by applying non-letter of credit principles, the implication of the UCP�s assumption of the law in practice, the resulting marginalisation of local laws, and the inequality in bargaining power between banks and applicants that precludes a choice of law other than the UCP. Chapter 3 explores the independence principle and question of documentary compliance, why the system is ridden with non-compliant documents and the lack of incentive and meaningful duty for the banks to check for �red flags� that may indicate fraud on the documents or in the transaction. It will be emphasised that documentary validity, rather than mere documentary compliance, should be the focus under the letter of credit. Chapter 4 examines the fraud exception to the independence principle, the typical high thresholds of proof that applicants had to overcome to estopp payment, and explores recent trends towards the gradual lowering of such thresholds. Finally, Chapter 5 considers practical measures and proposals for reform that would help to redress the imbalance in the allocation of risk identified in the thesis.

The purpose of this study was to attempt to enhance performance in the Australian Mathematics Competition of a group of Western Australian Year 9 students, to a level beyond that which they might have been expected to attain, through the use of a heuristic-based intervention technique using Vygotsky's zone of proximal development principle.Since 1978, students of mathematics in Australian high schools have been meeting the challenge of the Australian Mathematics Competition. This national competition aims to provide students with a sense of achievement in mathematics and to emphasise the importance of this subject in the high school curriculum.Vygotsky's zone of proximal development refers to the difference between a student's actual developmental level and the student's potential developmental level given adult assistance. In effect, this means that while students may achieve to a plane commensurate with their actual developmental level, they will progress into their zone of proximal development with assistance and their level of achievement will rise. Vygotsky's concept of Intervention coupled with Siegler's concept of heuristic-based strategy learning provided a methodology suitable for enhancing and maximising developmental effects in this study.The study involved three distinct stages: the preparatory phase, the treatment phase and the concluding phase.In the preparatory phase, student's actual developmental levels were determined based on their performance in the 1979 Junior level Australian Mathematics Competition paper. This data facilitated identifying the paths that learning should follow in order that students' problem solving skills should improve. During this phase, students also attempted an Australian Council for Educational Research (ACER) test entitled 'Test's of Reasoning in Mathematics' (TRIM). This measure was used to monitor expected development ++ / in mathematics reasoning ability for students over the period of the study.The treatment phase involved the students in over 35 hours of instruction which exposed them to a heuristic-based intervention technique designed to enhance their performance in problem solving. Students practised various problem solving techniques and the Australian Mathematics Competition ittself became the focus for improved performance.An index of improvement was provided in the concluding phase of the study by scores obtained from the treatment group on the 1982 Intermediate level Australian Mathematics Competition paper. Scores were significantly higher than the national average of either the Year 9 or Year 10 groups. The second ACER 'TRIM' test verified that the students achieved their expected development in mathematics reasoning ability during the study.The implication of this result is that the practice of restricting students to year groups or courses on the basis of age should be examined in the light of the Vygotskian principle.

Thesis (PhD)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: The implementation and verification of a recently proposed Huy gens' principle in hollow lossless waveguide is described. The extended Huygens' principle is applicable to the scattering effect of arbitrary obstacles in waveguide and allows the coupling of a volume Finite Element discretization with a quasi Method of Moments surface element approach. A review of the technique is given and expressions for the two port scattering parameters are derived. The implementation is restricted to posts in rectangular waveguide, although the technique may also be applied to general scattering problems in waveguide. Finite Elements for the volume of the obstacle are selected and a basis set is proposed. The elemental finite element matrices are derived for a low and higher order basis set, while the validity of the derivations is established by considering a simple waveguide example. A coupled set of matrix equations is constructed that can be solved for the unknown surface electric and magnetic fields and the volume magnetic fields. A set of test examples is chosen to verify the implementation. The convergence behaviour is examined for two test cases. The dissertation concludes with an evaluation of the technique and recommendations for future work. / AFRIKAANSE OPSOMMING: Die implementasie en verifiëring van 'n onlangs voorgestelde Huygens beginsel in leë golfleier word beskryf.
